HELP PLEASE. One side of my testitcles tenderness.?

I was sleeping when adjectives of a sudden it ached and in a minute I can't sleep. I'm 16 and I masturbate and I work out, what could be the cause of this? It's the first time it's happen and I'm very worried it could be something serious. Anything I can do besides seeing a doctor? If your ball hurt its 2 things choking the chicken or to much weights. Try to stay away from both for a while.
If it doesnt go away, don't be shy step to the doctor.. I am not a man so , I am wondering if you accidently layed wrong or hit it in your sleep
